I have printed this model with Ultimaker white PLA. I used 0.15mm layer height and, 18% infill. I used a 0.4mm nozzle with my extruder at 210 degrees Celcius. I used a heated bed. i did use a skirt, just cause i wanted to. Don't hesitate to use your own configuration....no worries!
What did i do?
I picked the horse logo from my browser and have put it in svg format in inktscape. Opened the svg file* in blender and made it a 3D object. In meshmixer i scaled the model. Than i first repaired the 3D model of the horse in netfabb. Than after opening up the fixed file in 123D design i used a cilinder to make a hole in the horse's head. First fixing the model in netfabb made it a whole lot easier. After that i fixed it again in netfabb and sliced it for printing.
If you would like to know how i design a 2D picture (google) into a 3D model.
